The apostolate of Saint Dominic Chapel is to provide Catholics throughout the Metro Detroit area with a thoroughly Catholic atmosphere in which to practice the Faith. In order to achieve this purpose, Vatican II and its reforms are firmly rejected as being at variance with the authentic Magisterium of the Roman Catholic Church.

Only clergy who have been duly ordained in the traditional rites of the Church are permitted to celebrate Mass, administer the sacraments and preach at Saint Dominic Chapel.
